What does Displacement mean?
Meaning of "Displacement"
The weight in tons of the water displaced by a ship. This weight is the same as the total weight of the ship when afloat. Displacement may be expressed either in cubic feet or tons, a cubic foot of sea water weighs 64 pounds and one of fresh water weighs 62.5 pounds, consequently one ton is equal to 35 cubic feet of sea water or 35.9 feet of fresh water. The designed displacement of a vessel is her displacement when floating at her designed draft.
